Estimated revenue lost to missed calls
$5,413 a month
That's $64,950 a year, or about 11 lost customers a month.
Formula: missed calls per week × 4.33 weeks × % that would have become customers × customer value. An estimate based on your numbers, not a guarantee.
Why missed calls cost more than you think
A missed call isn't just one lost conversation. For local and service businesses, the person calling is often ready to book right now. If nobody answers, many callers don't leave a voicemail. They call the next business on Google instead.
The cost adds up quickly because it repeats every week: during appointments, lunch breaks, busy mornings, evenings and weekends.
How to use the result
- Check your phone system or call log for a week to find your real missed-call number.
- Be conservative with the share of callers who would have become customers. Even 10% to 25% is usually meaningful.
- Use the value of a customer over time, not just the first purchase, if customers usually come back.
- Compare the monthly loss with the cost of fixing it.
Ways to stop missing calls
- Call forwarding: sends calls to a mobile, but still depends on someone being free.
- Live answering service: people answer for you, usually charged per minute or per call.
- Extra staff at peak times: effective, but the most expensive option.
- AI receptionist: answers every call 24/7, answers common questions, books appointments and passes urgent calls to your team. See what an AI receptionist costs.

Frequently asked questions
How do I calculate the cost of missed calls?
Multiply the calls you miss per week by 4.33 to get a monthly figure, then by the share of those callers who would have become customers, then by the average value of a customer. For example, 10 missed calls a week × 4.33 × 25% × $500 is about $5,400 a month.
How many calls do small businesses miss?
It varies a lot by industry and staffing. Busy practices, trades and agencies often miss calls during appointments, lunch breaks, peak hours and after hours. Check your phone system's call log for a week to get your real number.
Do people leave voicemails when a business doesn't answer?
Many don't. A caller who reaches voicemail often hangs up and tries the next business in the search results, especially for urgent or local services.
How can I stop missing calls?
Common options are call forwarding to a mobile, a live answering service, an extra receptionist at peak times, or an AI receptionist that answers every call 24/7, books appointments and passes urgent calls to your team.
Is the calculator result a guarantee?
No. It applies the numbers you enter and shows what they imply. Your real figures depend on your call volume, the type of callers and how well you follow up.
